23 and 24 are, as shown, placed upon opposite sides of a 75 rectangular hole 2 5 in the table 20. Resting upon the lower frame 23 is a rectangular upper frame 27, and resting upon the lower frame 24 is a corresponding upper frame 28. Each upper frame 27 and 28 has inserted through slots-29 in its lower portion cap screws 30 enter-' 80 'ing its adjacent lower frame, so that it may be adjusted horizontally with reference to its 'lower frame under the control of the set screws '31 and 32. Journaled in suitable stationary bearings 'upon the frame 27 'is a shaft 33, carrying a roller 34. 'Directly oppositethis shaft 33 is a corresponding shaft 35\.j`o`1`1 rnaled upon the upper frame 28 and carrying a roller36.' Slidably secured upon inner faces of the upper frame 27 and above the roller V34 are plates 39 adaptedfto-nve up and down under the control of springs 40 contrlled by screws 41, as shown in Fig. 17. Theseslidable plates 39 are secured to the frame 27 by means of the cap screws 42 passing `through vertically-"elongated slots 45 in the plates ,39, the adjustment of thief'cap screws being such that the plates 39 may be moved up and d own with reference to the frame 27 as described. Each ofthe two plates 39 just described carries On its lower portion a suitable bearing for a shaft 43 on which is mounted an upper roller 44 normally held by the springs 40l in contact with the roller 34 heretofore described. Identical 1'00 parts consisting of plates 46, cap screws 47, springs 48, adjusting screws 49, shaf 50 and roller 51, are provided upon the upper frame 28. All of the parts just described i are so arranged that the roller 5l is held by the spring 48 n contact with the roller 36. The mechanism just -105- l Suitably journaled' in the frame of the machine is a 110 main power shaft 55 carrying a suitable wheel 56 or 'knives 86 and88 upon their respective upper rollers other suitable mechanism through which power may be communicated from an eXternal'source thereto. On this shaft 55 is a gear 57 meshing with a gear 58 upon shaft 35. This gear 58 meshes with gear 59 upon the shaft 33, which, in turn, meshes with another gear 60 on the shaft 43. On the shaft 50, heretofore described, is another gear 61, which meshes with the gear 58, but does not mesh with the gear 60. These gears 58, 59, 60, 6l are all the same size, so that when power is coml municated to them from the shaft55, they all rotate at the same speed, and consequently the four shafts 33, 35, 43 and 50, rotate at the, same speed, with the result that their corresponding rolls 34, 44, 36 and 51 also rotate at equal speeds. Extending from the upper frame 27 is an arm 63 carrying a shaft 64 on which is 'journaled an idleflanged guide roller 65. Similarly extending from the upper frame 28 is an arm 66 carrying a shaft 67 and a guide roller 68.

Pivoted on suitable bearings 70 upon opposite sides of the upper frame 27 are bell-crank levers 71. The shorter arms of these bell cranks are connected by a rod 72 on which is journaled a roller 73, preferably of rubber or other yielding material. 'The longer arms of these bell cranks are connected to the upper frame 27 by suitable retractile springs 74, which serve to hold the rol-ler 73 in contact with the roller 34, as is 'best shown in Fig. 5. Similarly pivoted on suitable bearings 75 upon tlie upper frame 28, are other bell cranks 76. On the shorter armsof these bell cranks is a rod 77 on which is jounialed a roller 78 corresponding to the roller 73 heretofore described, said roller being held in contact with the roller 36 by means of the retractile spring79 corresponding to the spring 74, heretofore described.

In roller 34 I cut four rectangular grooves running the length of the roller, two of them, 81, being empty, as shown, and two of them, 82, being lled with flexible Iii the roller 36 I cut two corresponding empty grooves 83, and two compressible material filled grooves 84; The empty grooves of each roller are staggered with reference to the empty grooves of the adjacent roller, and the filled grooves of each roller are staggered with reference to the filled grooves of the adjacent roller, withvthe result that a filled-groove 82 Y of the roller 34 will always meet or mesh with an empty groove 83 of the roller 36, as shown in Fig. 6, and a filled groove of roller 36 will always meet or mesh'with an empty groove of roller 34, as shown in Fig. 7.

In the ppper roller 44 adjacent to the roller A34, I mount at intervals 180 apart,-two cutting knives 86 adapted to` mesh, as'shown in Fig. 6, "with Van empty groove s81 of'the roller34. Midway between these `knives 86 upon the roller 44 I place two creasing knives 87 adapted to mesh with the filled grooves in the roller34, as shown at the left of Fig. 7. Similarly lI mount upon the roller 51 other cutting knives 88 are staggered with reference to each other, and that the creasing knives are correspondingly staggered, with the result that when a continuous strip of paper 91 is fed under the tension rollers 73 and between the rollers 34 and 44, and another strip of paper 92 is fed under the tension rollers 78 and between the rollers 36 and 51, the strip of paper 91 will be cut, as shown in Fig. 6, at the same time the strip of paper 92 is being creased between rollers 36 and 51, that when the paper has .moved from the position of Fig. 6 to that of Fig. 7, the paper 92 will be eut while the paper 91 is being creased, and that when the strips of paper are fed downward between the rollers 34 and 36 and cut across the strip, the cut ends of the strip of paper will always meet or mesh with a creased portion of the adjacent strip of paper. Paper is supplied to the niachine as best show-n in Fig. 5 from suitable rolls 1ocated at any convenient points adjacent to the machine; the end of one strip being passed over the roller 65, thence under the roller 73, and thence be tween the rollers 34 and 44 in the manner described, while the end of the other strip of paper is passed over the roller '68 under the roller 77, and thence between the rollers 36 and 50 in the manner described. After the paper in these two strips 91 and 92 has been cut and creased in the manner described, in passing between their respective sets of vertically vdisposed rollers, it is necessary to cause them to pass smoothly between the lower pair of rollers 34 and 36, and in order to accomplish this purpose, I provide mechanism which will now be described.

I secure to one of the upper frames 27 or 28, in the particular case here illustrated',I the frame 28, a pair of horizontal arms 93 having their outer ends connected by a horizontal rod 94 lying in the vertical central -plane of the machine above the centers of the shafts 33 and 35. Upon this rod 94 I secure by set screws 95 a plurality of triangular guides 96`having their lower angular faces 97, 98 curved, so as to conform, as b est shown in Figs 6 and 7, to the surfaces of the rollers 34 and 36, there, however, being sufficient space bc- -tween the guide and rollers so that the paper strips 91 and.92 may pass, as shown and heretofore described.

In order to be sure that the end of each piece of paper 91 which has been out off in passing between the rollers 34 and 44 will pass in between the guide l96 and roller 34, as illustrated in Fig. 6, I provide pon the roller 44 adjacent to each cutting knife 86, a horizontal rod or shaft 100, on which, intermediate betweenv the ends of the roller, are rigidly secured a plurality of normally outwardly pointing lingers 101 lying in the circumferential grooves 102 in said roller 44. These fingers 101 between the ends of the rollers are normally held outward by springs 103 attached to an end finger 104 at the end of the rod 100, and preferably beyond the end of the roller 44. This end finger 104 has in its outer end a small anti-friction roller 105, best shown in Fig. 5, which is adapted to travel upon a cam 106 located, as shown in Fig. 6, so that as this roller 105 travels over the cam 106 it will, lthrough the agency of its lever 104 and the shaft 100', move the fingers 101 from their outwardly extending position into the position shown in dotted lines at the left of Fig. 6 in which they are wholly within the grooves 102, and do not interfere -with the roller 44 rotating in contact with the roller 34.

The operation of this part of the mechanism is that, as a cutting knife 86, to which a particular set of fingers 101 is adjacent, reaches the position of Fig. 6, where it cuts a portion of paper 91 from the continuous strip, the fingers 101 are held inside of. the circumference of the roller and do not interfere with its operation, but just as soon as the knife 86 passes in a counterclockwise direction slightly beyond the position shown in Fig.

Y 6, the roller 105 is released from the cam 106, which,

in turn,- releases lthe ends ofthe fingers 101 sufficientlyy lthe machine cuts off two portions'of paper from the main roll ofl paper ateach revolution of the roller, 41 provide one set of fingers 101 forjeach knife 86 upon the roller 44. Similarly, I provide upon the upper roll 51 a plurality of shafts 108, fingers 109, an end finger 110 carrying a roller 111 adapted to travel upon a cam 112, adapted to cause the foregoing parts to operate with reference to the roller 51 andvroller r36, exactly as cam 106 caused the mechanism of rollers 34 and 44 to operate.

As heretofore stated, the set screws 41 and 49 and the springs 40 and 48 and their attachedmechanisrn control the pressure of the upper rollers-upon the lower rollers,` and the pressure between the two lower rollers 34 and 36 may be regulated by one or both of the set screws31.` A, '\j

In order to insure the pieces of cut and creased paper passing in contact with each other from the foregoing mechanism, which will be hereafter referred to as the creasing and cut ing mechanism, to the folding and pressing mechanism,l provide below the rollers 34 and 36, and adjacent.to the guides 96 a plurality of strippers 114. These strippers 114 are mounted upon supporting rods 115 and their upper ends or points 116 enter grooves 117 in the lower rollers, as is best shwn Fig. 6 so that it is impossible Vfor the paper4 coming from between the lower rollers to` cling to thel surfaces of said rollers, and the portions of paper must pass downward between the strippers, as is shown in Figs. 6 and 7, to the folding and pressing mechanism, which will now` be described.

. It is particularly important to be able vto adjust the pressure between the rolls 34 and 36, so as to maintain a pull upon the paper strips 91 and 92 to draw them through the cutting and creasing mechanism and to.

feed them down into the folding mechanism. It is also'desirable that tensionbe maintained here in order to, in combination with the -`tension exerted by the;

rolls 73 and 78 heretofore described, stretch the strips of paper 91 and 92 over the lower rolls 34and 36, as shown, s o that when the strips of paper are engaged by the cutting or creasing knives, and particularly the cutting knives, as shown in Figs. 6 and 7, the operation designed to be performed by these knives upon. the papei is readily performed. p

Cutting md pressing mechanism-Rigidly secured in suitable bearings 120 and 121 is a strong shaft 122, to, which is rigidly secured by any suitable means the back 123 of an oscillating box or chute having the side walls 124 and 125. This chute is, as shown, open at the i ychute, but, in practice, I find that after a few inches of the folded paper product has started down the chute, the friction of the product upon the walls of the chute is sufficient to maintain the column of prodlct in proper form without such a device. In order to oscillate the shaft 122, and consequently the chute, just described,

I rigidly secure to said shaft 122 by any suitable means, an upwardlyextending crank-arm 127 having in its 'upper end a slot 128 in which a bolt 129 is adapted. to

be secured in different positions. Journaled upon this bolt 129 is a short connecting rod 130, having itsy other end journaled upon a crank pin at the end of a crank arm 132. Thisl crank' arm 132 is mounted` upon a shaft 133 which carries a pinion 134 meshing with a gear 135, which is twice its size,mounted upon the shaft of one of the rollers heretofore described. The reason for this proportioning of the gears 134 and 135 is that, las will hereafter appear, the chute must make two oscillations in order to take care of the two small pieces of paper coming from each lower roller 34 and 36 during their complete revolution. If these lower rollers were designed to only produce one small The walls of soy mechanism just described s so proportioned that the chute first assu/mes the position of Fig. 6 when the `middle kof one piece of product paper and the end of another piece of the" same have come from the cutting and creasing mechanism to a pointadjacent to one edge of the chute, and are ready to be folded; and that as said pieces are folded the chute moves from the position of said Fig.v6 to that of Fig. 7, in which the next suc cap screws, in such a manner that theyv may be moved slightly up and down in av'ertical plane, are one or more horizontal, pointed latchl members 141, extending as best shown in Fig. 9, through a suitable slot or slots .142 .in the wall 125. These latch membersl 141 are yieldingly held in position with their pointed ends* elevated by means of a retractile spring or springs 143. Smilarly,l provide adjacent to the wall 124 of ,the chute a shaftv 145, lever arms 146 carrying cap screws 147, under which are mounted latch members 148 adapted to pass through slots 149 in the `wall 124,

i 11. This lever arm and its connected mechanism just described, is, as is bestshown in Fig. 8, in the same vertical plane with a lever 159 loosely journaled upon .the

shaft 145. On the `shorter end of this lever 159 isan v inclined angular face 160 bearing against theface of the latch 155, heretofore described. The longer end of the lever 159 is adjustably controlled and limited in motion by the adjustable stops 161 and 162. Similarly mounted upon the shaft 145, there is another short le-v Vver arm 163 corresponding to lever arm 153, having a latch 165 corresponding to latch 155. Opposite this lever arm 163 and latch 165 there is journaled upon the shaft 138 a lever 169 having an angular face 170 adapted to bear against the face of the latch 165exactly in the j same way that the face169 of the Vlever 159 bears upon the face of the latch 155, This lever 169 is limited and controlled by adjustable stops'167 and 168 corresponding to the stops 161 and 162, heretofore described. i

The parts just described are normally held in the vposition of Fig. 6 by means of a spring 171 connected lat the upper end to astationary arm 172 etending. 'from the wall 124, and at the other end to the shaft 145. Similarly, the shaft138 is connected to a spring 173 vwhich has itsother end` connected to an arm 174 exv tending from the wall 125. `This spring serves to hold the latch 141 and attached mechanismnormally in the position of Fig. 9. y l Y Y,

Assuming now that the parts just described are in the position of Fig. 7 the spring (not shown) corresponding to spring 156 throws the latch 165 outwad to the position of Fig. 7, in which position it is/in the way of the extreme point of the face 170 of the lever 169. When, now, the oscillation of the shaft 122 starts to rock the chute from the position of Fig. 7 to that of 6, the point of the' face 17() is engaged by the lower corner of the latch 165. The first result of this is to move the lever 169 upward to the position of Fig. 9, in which position its-longer end 169cis stopped by the stop 167, As the latch 165 still engages the point of the face 170 of this lever, it follows that the lever 163 must move the lever-arm 146 toward the position lof Fig. 9.A When lthis position lis reached and slightly passed, the point of the latch 165` clicks off from the point of .theface 170 of theleverr169, and the lever 146 immediately swings back under the action of spring 171 to the position of Fig. 6, with the result that the latch 148 is quickly slipped, as shown in Fig. 6,.over the paper which has just been folded, a'nd holds it down, so that the folding or pressing lever 176,A which will be hereafter described, may be removed. The lever and latch mechanism controlling the latch 141,v operates, in exactly the same manner as the mechanism just described, except that it operates just as the mechanism reaches the position of Fig. 7.

Pivoted to the arm or arms 172, heretofore described, Ais a suitable shaft 177 onvwhich are a plurality of short lever arms 176 adapted to enter the wall 124, heretofore described, through suitable slots open at their tops, and travel downward from the position of Fig. 7 to that of Fig. 6, to press down the paper within the chute. l

Adjustably secured to the shaft 177 which carries these levers 176, by means of a set screw 178, as is best show`n in Fig. 8, isa longer lever 179, having its end 180 adapted to travel backward and forward upon the top of the `table 20, said table performing the functions of a cam to move the lever 179 and the attached levers 176, from'the position of Fig. -7 to that of Fig.

6 and back again,`as the chute makes a complete oscillation, as heretofore described. Similarly 1 mount upon a suitable shaft'or bearing 182 carried by one or more arms 174, a plurality of short, presser lever arms 183, adapted to enter the wall 125 of the chute, and pressdown the paper therein, as shown in Fig. 7, said lever arms 183 being connected by'suitable set screw mechanism corresponding to set screw 178 to a lever 184,`having its end 185 adapted to travel on the table exactly as the end 180 of the lever 179 does, and for the same purpose.

In the complete operation of the folding and press ing mechanism, as thus far described, the cutting and creasing mechanism feeds down properly creased and cut paper, as heretofore described, into the chute in the position of Fig. 6, with the two adjacent cut ends of one strip of paper adjacent to the crease of the other strip of paper, and all in the corner over the latch 141 and adjacent to the wall 125, as shown in Fig. 6. As the chute now begins .to oscillate toward the position of Fig. 7, the short lever arms 183 are moved to the position of Fig. 7. As soon as thisroccurs, the latches 141 are withdrawn as described, and snapped in again over the freshly folded paper and below a plate 186, which covers the lower face oflthe lever arms 183. While this operation has been going on, morepaper has been fed down, so that the next adjacent crease and adjacent cut edges of the combined strips of paper are in the corner over the latch 148, and adjacent to the wall,124, as shown in Fig. 7. i The chute now starts to oscillate in the opposite `direction, with the result that the plate 187 on the lower face of the lever arms 176 travels along the incoming paper, and presses it down to the position of Fig. 6, after which the latches 148 are withdrawn and snapped in again as heretofore described. y

1n attempting to operate the machine at a high rate of speed, and secure the operation just described, l have found great difficulty with only the mechanism just described, in causing thepape'r to reach the desired corners described, so that accurate folding may take place. 1 therefore provide an air blast mechanism Which supplies, at the proper instant, a blast of air or other gas to blow the paper into proper position. This mechanism will now be described'. In order to accomplish this bbject, I journal in suitable bearings 188 and 189 formed in the opposite side frames, two horizontal pipes 190 and 191 best shown in Fig. 8.

`The ends of these pipes,` are so mounted that they form bearings about which these pipes and mechanisms attached thereto may oscillateur rock in a vertical plane within reasonable limits. Extending from the pipe 190y are two small blast pipes 192 and 193 having their ends or nozzles 194 and 195 turned inward. These ends 194,

195 are so located and the curvature of their ends is `such, that, as shown in Figs. 7 and 8, air issuing from them will strike the creased and cut paper coming into the foldillg mchanism, in such a position that the blasts of air tend tofdrce the paper'into the position of Fig.v 7. This is accomplished quite largely by reason of the fact that the inwardly turned jets strike the opposite outer edges of the paper to be folded, at an angle and the air after'leaving the nozzles travels outward toward the opposite edges of the paper. Similarly, from the pipe 191 I provide other blast pipes 196 and 197 having inwardly turned ends 1.98 and 199, so locatedthat, as shown in Fig. 6, they. strike the paper when it is in the position ofthat figure just ready to be 1 5 folded. ,Iournaledin suitable bearings upon the upper frame of the machine, and outside of the bearings for the pipes 190 and 191, I mount two shafts 200 and 201, carrying eccentrics 202 `and 203, in which rest the supply pipes 204 and 205 for the pipes 190Qind 191, respectively. On these shafts 200 and 201 are mounted sprocket pinions 206 and 207, connected by sprocket chains 208 and 209 with sprocket gears 210 and 211,

mounted respectively upon the shafts of the upper rolls of the cutting and creasing mechanism, as is best shown in Fig. 2. These eccentrics 202 and 203 are so located upon their resp/ective'shafts, that as theupper rollers of the cutting and creasing mechanism revolve, these eccentrics cause the pipes 204 and 205 to-move'up and downv in a verticalplane a sufficient distance so that the ends 192 and 193 and 198 and 199 of the various blast pipes follow the paper which is being folded in adjacent to them, and cause the -air escaping from them to strike the paper at just `the right position as it is vfolded in, and follow it downward a sufficient length of 35 time to allow it to be folded.

The outer end of the pipe 205 is connected by Vmeans of a ilexible'pipe 213 with the casing 214 of an air supply valve, having extending from its upper end a valve rodl 215 adaptedto be moved up and down to control 40 the passge of air from a main supply pipe 216 thrqugh the casing 214 to the pipe 213. Similarly, the pipe-204 is connected by a flexible pipe 217 to a valve casing 218, containing a rod 2,19 controlling' the passage of air from thepipe 220 to the pipe 217. The pipes 216 and 2,20 are connected by a pipe 221 to any convenient source of compressed air. Rigidly secured to the shaft 122, heretofore described, is a vertically extending lever arm.222, carrying upon `its upper end horizontal arms 223 and 224 the arm 223 being adapted to en- 5 0 gage the valve stem 215, and the arm 224 being adapted to engage' the valve stem 219, heretofore described. These rods 223 and 224 have a slotted connection with the lever arm 222, by means of the slots 225, and bolt 226, so that they may be adjusted to this vertical position upon the arm '222. They are also so shaped that only one of them touches its adjacent valve stem at a time. The entire mechanismis so proportioned with reference to the othery parts of the machine, that the lever arm 123 will-operate the valve stem 215 at the proper time to admit air throughthe nozzle ends 194 and 195, when it is desired that air shall be so admitted for the purpose of assisting the folding operation on one side of the machine, as heretofore described, land that the lever arm 224`will operate the valve 219 at the proper time to admit air through thenozzle ends 198 claims.

- a paper approaching the machine over large rollers 68 and 65, respectively. When, now, a moderate quantity of steam or other similar moist gas is allowed to escape from the ends of these pipes under the paper vpassing over these rollers, it will moisten the same sufciently to take out any excessive stiffness, and render the operation of the machine upon-the paper more easy and satisfactory. v

It will be Vnoticed that the Width of paper operated upon by the machine has not been specified, and the same forms no portion of my invention. By making the cutting and creasing rollers of suicient width and the chute f corresponding dimensions, and correspondingly increasing the number of folding ingers extending crosswise of the machine, almost any desired width of paper may be operated upon by the device of my invention. ,y

While I have described the cutting knives 86 and 88 as wholly severing the strips of paper 91 and 92 on which they act it is manifest that only a perforation for severance of the paper may be made without departing from my invention. j 95 It will be noticed that eachoriginal strip of paper 91 and 92 is, irrespective of its `being cut up into short pieces, ultimately folded in zigzag form into the chute. For convenience this term will be used in some of the What I claim as new and desire to secure by Letters Patent, is:
